marina corporate dubai real-estate

The AS handle PORTOMONTENEGRO-AS is held by Adriatic Marinas d.o.o.

What it's used for

  • The address space carries the corporate network for the Porto Montenegro marina complex, as indicated by the netname NET-PORTOMONTENEGRO and registrant Adriatic Marinas d.o.o.
  • The inventory consists of a single IPv4 prefix, 91.220.187.0/24, comprising 256 addresses, with 0 IPv6 prefixes announced
  • With only 1 observed neighbour, this is a stub network providing connectivity for the marina's internal operations, guest Wi-Fi, and administrative systems rather than transit or broad residential access
  • Traffic from this AS consists of web browsing, VoIP, and IoT device traffic from marina guests, staff, and operational systems within the Porto Montenegro development

Notable

  • The registrant Adriatic Marinas d.o.o. matches the AS holder, confirming direct ownership of the address space
  • Adriatic Marinas d.o.o. is a wholly owned subsidiary of the Investment Corporation of Dubai (ICD), the principal investment arm of the Government of Dubai
  • The address inventory is minimal, consisting of a single /24 block, which is typical for a private corporate estate serving a specific physical location rather than a public ISP

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
